Is The Pink Stuff Foaming Toilet Cleaner Septic Safe?
Let’s begin by looking at its ingredients:
Ingredients:
INCI Name: C9-11 Pareth-6, Cocamine Oxide, Propylene Glycol Butyl Ether, Tetrasodium GLDA, Benzalkonium Chloride, Mixture, Acid Red 52, Citric Acid
None of these ingredients appear to be harmful or overly harsh for the bacteria in your septic system. The only ingredient that raises some concern is citric acid. While it’s true that acidic substances are generally not recommended for septic systems, citric acid is considered a weak acid, especially when compared to the stronger acids typically found in commercial cleaning products.
Although citric acid may kill some surface bacteria where it’s applied, it is unlikely to reach your septic tank in a concentration high enough to cause harm. Once diluted with water and flushed away, the citric acid becomes even weaker and poses little to no threat to the beneficial bacteria in your septic system.
Verdict:
Based on its ingredients and their expected concentrations, The Pink Stuff Foaming Toilet Cleaner—along with other products in The Pink Stuff range (according to the brand’s website)—appears to be generally safe for use with septic tanks, leach fields, and sewage treatment plants.
